[0027] In the description of the present invention, unless otherwise specified and limited, it should be noted that the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection between two components.

[0028] like Figures 1 to 6 As shown, the water-cooled condenser of the present invention includes a condenser 100. The condenser 100 is provided with a refrigerant chamber 200 and a cooling chamber 300 which are independent of each other. The refrigerant chamber 200 is used for circulating refrigerant, and the cooling chamber 300 is used for circulating cooling water. The cooling water circulating in the cooling chamber 300 exchanges heat with the refrigerant circulating in the refrigerant chamber 200, thereby cooling the refrigerant by water cooling. The condenser 100 is spirally coiled to form a water storage frame for containing defrost water. The water storage frame replaces the original evaporating dish inside the refrigerator, and the defrost water flows into the water storage frame. The refrigerant circulating in the refrigerant chamber 200 exchanges heat with the defrost water at the same time, thereby evaporating the defrost water in the water storage frame.

[0029] Specifically, the condenser 100 is spirally coiled along the height direction and stacked layer by layer to form a sealed rectangular, elliptical or circular water storage frame. The condenser 100 is installed in the compressor cabin, and the bottom of the water storage frame is sealed and connected to the bottom plate of the compressor cabin, thereby forming an upward-opening water storage space. The defrost water flows into the water storage space, and the heat of the refrigerant flowing in the refrigerant chamber 200 is used to evaporate the defrost water.

[0030] The condenser 100 includes an air inlet 102a and an air outlet 102b located at both ends of the refrigerant chamber 200. The high-temperature and high-pressure refrigerant flows into the refrigerant chamber 200 from the air inlet 102a, exchanges heat with the cooling water in the cooling chamber 300 to cool down, and then flows out from the air outlet 102b; the water inlet 103a and the water outlet 103b are located at both ends of the cooling chamber 300. The cooling water flows into the cooling chamber 300 from the water inlet 103a, exchanges heat with the refrigerant in the refrigerant chamber 200 to heat up, and then flows out from the water outlet 103b.

[0031] Preferably, the flow direction of the refrigerant in the refrigerant chamber 200 is opposite to the flow direction of the cooling water in the cooling chamber 300, thereby increasing the heat exchange efficiency between the refrigerant and the cooling water.

[0032] Reference Figure 3 In one embodiment, a partition plate 101 is provided in the condenser 100, and the partition plate 101 divides the inner cavity of the condenser 100 into the refrigerant cavity 200 and the cooling cavity 300. The refrigerant cavity 200 is located on the inner side of the water storage frame, so as to contact and exchange heat with the defrost water in the water storage frame.

[0033] The condenser 100 is a flat tube, and its cross section is approximately rectangular. Its radial length along the height direction is greater than its radial length along the width direction. The partition plate 101 divides the inner cavity of the condenser 100 into the refrigerant cavity 200 and the cooling cavity 300 along the height direction of the condenser 100, thereby increasing the heat exchange area of ​​the refrigerant cavity 200 and the cooling cavity 300. The refrigerant cavity 200 is located on the inner side of the water storage frame, that is, the inner wall of the water storage frame is the outer wall of the refrigerant cavity 200.

[0034] In this embodiment, the air inlet 102a is located at the bottom of the water storage frame, the air outlet 102b is located at the top of the water storage frame, the water inlet 103a is located at the top of the water storage frame, and the water outlet 103b is located at the bottom of the water storage frame, so that the flow direction of the cooling water is opposite to the flow direction of the refrigerant, and the high-temperature and high-pressure coolant flows into the refrigerant chamber 200 from the air inlet 102a, flows from bottom to top along the refrigerant chamber 200 and simultaneously exchanges heat with the cooling water in the outer cooling chamber 300 and the defrost water in the inner water storage frame, and the coolant after heat exchange and cooling flows out from the air outlet 102b; the cooling water flows into the cooling chamber 300 from the water inlet 103a, flows from top to bottom along the cooling chamber 300 and exchanges heat with the refrigerant in the inner refrigerant chamber 200, and the cooling water after heat exchange and heating flows out from the water outlet 103b.

[0035] Furthermore, the water-cooled condenser also includes a metal base plate 400 connected to the bottom of the water storage frame, the metal base plate 400 and the water storage frame form a water storage space that is open upward, the metal base plate 400 is sealed to the water storage frame, and the water-cooled condenser is fixed in the compressor cabin through the metal base plate 400, thereby facilitating the installation of the water-cooled condenser.

[0036] The metal bottom plate 400 is made of a metal material with good thermal conductivity, such as copper, aluminum, etc., and the heat of the refrigerant in the refrigerant chamber 200 is transferred to the defrost water in the water storage space through the metal bottom plate 400, thereby accelerating the evaporation of the defrost water.

[0037] It should be particularly noted that the pipe section at the bottom of the condenser 100 that is connected to the metal bottom plate 400 only has the refrigerant chamber 200, that is, the partition plate 101 is cancelled, and the air inlet 102a of the refrigerant chamber 200 is located at the bottom of the water storage frame, and the high-temperature and high-pressure refrigerant enters the refrigerant chamber 200 from the air inlet 102a. Since the pipe section connected to the air inlet 102a only has the refrigerant chamber 200, the heat of the refrigerant in a high-temperature state can only be transferred to the defrost water in the water storage space through the metal bottom plate 400, thereby ensuring that there is sufficient heat to evaporate the defrost water.

[0038] Reference Figure 4 ,and Figure 3 The only difference between the water-cooled condenser shown is that the condenser tube 100 includes a refrigerant tube 102 and a cooling tube 103 sleeved in the refrigerant tube 102 , the cooling cavity 300 is located in the cooling tube 103 , and the refrigerant cavity 200 is located between the cooling tube 103 and the refrigerant tube 102 .

[0039] The condenser 100 is a sleeve, including a refrigerant tube 102 and a cooling tube 103 located inside the refrigerant tube 102, the air inlet 102a and the air outlet 102b are respectively located at the two ends of the refrigerant tube 102, the water inlet 103a and the water outlet 103b are respectively located at the two ends of the cooling tube 103, the high-temperature and high-pressure refrigerant flows from the air inlet 102a into the refrigerant cavity 200 between the cooling tube 103 and the refrigerant tube 102, the cooling water flows from the water inlet 103a into the cooling tube 103, and the refrigerant in the refrigerant cavity 200 simultaneously exchanges heat and cools down with the cooling water in the cooling tube 103 and the defrost water in the water storage space outside.

[0040] The pipe section at the bottom of the condenser tube 100 connected to the metal bottom plate 400 is only provided with the refrigerant chamber 200, that is, the cooling tube 103 inside the refrigerant tube 102 is eliminated, so that the heat of the refrigerant in a high-temperature state can only be transferred to the defrost water in the water storage space through the metal bottom plate 400, thereby ensuring that there is enough heat to evaporate the defrost water.

[0041] Reference Figure 5 and Figure 6 ,and Figure 3 The only difference between the water-cooled condenser shown is that the condenser tube 100 includes a refrigerant tube 102 and a cooling tube 103 arranged along the refrigerant tube 102, the refrigerant tube 102 is spirally coiled along the height direction to form a first rectangular frame, the cooling tube 103 is coiled along the outer wall of the first rectangular frame to form a second rectangular frame, the refrigerant cavity 200 is located in the refrigerant tube 102, and the cooling cavity 300 is located between the refrigerant tube 102 and the cooling tube 103.

[0042] The air inlet 102a and the air outlet 102b are respectively located at the two ends of the refrigerant tube 102, the water inlet 103a and the water outlet 103b are respectively located at the two ends of the cooling tube 103, the metal bottom plate 400 is connected to the bottom of the first rectangular frame formed by the coiling of the refrigerant tube 102 to form the water storage space for holding defrost water, the cooling tube 103 is open on one side facing the first rectangular frame, and the cooling tube 103 is sealed and connected to the first rectangular frame to form the cooling cavity 300 between the refrigerant tube 102 and the cooling tube 103 to facilitate heat exchange between the refrigerant and cooling water.

[0043] Furthermore, the height of the first rectangular frame formed by the coiling of the refrigerant tube 102 is greater than the height of the second rectangular frame formed by the coiling of the cooling tube 103, and the distance between the top of the second rectangular frame and the top of the first rectangular frame is less than the distance between the bottom of the second rectangular frame and the bottom of the first rectangular frame. In this way, the bottom of the first rectangular frame connected to the metal bottom plate 400 has only the refrigerant cavity 200, so that the heat of the refrigerant in the high temperature state can only be transferred to the defrost water in the water storage space through the metal bottom plate 400, thereby ensuring that there is enough heat to evaporate the defrost water. Preferably, the top of the second rectangular frame is flush with the top of the second rectangular frame.

[0044] The present invention also provides a refrigerator, which includes the above-mentioned water-cooled condenser, a compressor 500 connected to the refrigerant chamber 200, and a dew-removing pipe (not shown in the figure) connected to the cooling chamber 300, and the cooling water circulates in the cooling chamber 300 and the dew-removing pipe.

[0045] After being compressed into a high-temperature and high-pressure gas by the compressor 500, the refrigerant flows into the refrigerant chamber 200 from the air inlet 102a, and exchanges heat with the cooling water in the cooling chamber 300 and the defrost water in the water storage frame to cool down, and then re-enters the compressor 500 through the throttling element and the evaporator to complete the cycle; the cooling water in the cooling chamber 300 exchanges heat with the refrigerant in the refrigerant chamber 200 to heat up, and flows through the back of the refrigerator, the U shell and other locations where dehumidification is required through the dehumidification pipe, and the cooled cooling water flows back into the cooling chamber 300 again; the defrost water in the water storage frame exchanges heat and evaporates.

[0046] In summary, the present invention eliminates the traditional fan cooling and utilizes flowing circulating water to cool the condenser, which has better quietness. The spirally coiled condenser tube 100 replaces the evaporating dish to collect defrost water, and the water circulation and defrost water are used for two-way cooling. The water-cooled condenser replaces the fan, the traditional condenser and the evaporating dish, which has low cost and occupies less space.
